Cleansers, charging, heads and warranty: three facial cleansing devices
Last checked 2026-10-02.
Per FOREO's manuals, both LUNA 4 models should not be used with clay-based, silicone-based or grainy cleansers, need no replacement brush heads, and should not be used while charging. PMD's page for the Clean Pro RQ states none of these, so for it they are unknown rather than assumed; PMD's page does state a 20-year warranty against manufacturer defects.

Links that say “Buy from FOREO” go to FOREO's own store through the Awin affiliate network, and BeautyEvidence may earn a commission on purchases there too, at no extra cost to you. Each opens that model's page on foreo.com, where the sets on offer can differ from the Amazon listing this page describes.

Per FOREO's manuals, neither LUNA needs replacement brush heads; for the PMD, whether its head needs replacing is not stated. PMD's 20-year warranty covers manufacturer defects and excludes drops and incorrect voltage; a longer warranty is not evidence that a device lasts longer or cleans better.
Kinds of claim on this page: app functions, charging, water, cleanser rules and warranty are manufacturer claims, from the manual or maker page linked in each column (read 2026-10-02); sellers are from the Amazon US listings on 2026-10-02. No prices are shown: check the retailer for the current price. A cell no source settles says unknown (not stated). There is no product evidence about skin results here: nothing was measured or tested.
LUNA 4 link: the combination-skin listing (B0BFQJ1T75) had no featured new offer on Amazon US on 2026-10-18. The link now goes to the sensitive-skin version of the same LUNA 4 (B0BFQLHRXK), sold by FOREO and in stock on 2026-10-18. The FOREO LUNA 4 manual (read 2026-10-18) covers both and says the skin-type versions differ in their brush bristles. Its price is not shown.
Head to head: FOREO LUNA 4 vs LUNA 4 go. What needs the app: using a LUNA 4 without the app.
